So I've done a lot of searching and have even asked a couple FB groups this question, but I need a little more solid answers before I start pulling stuff apart. Does anyone know if 2001 - 2005 IS300 front end suspension arms are interchangeable with the 1998-2005 GS300?

I have a bunch of brand new suspension arms laying around from my IS300 which aren't selling, and was wondering if they'll work for my GS300. I don't want to just pull off arms off the car to compare with what I have without more solidified proof and/or experiences from others. Thanks in advance!
